The triboelectric energy generator (TEG) has been investigated during the last decade in terms of power improvement, however, its voltage is too high to be used directly as a power source. Although there was an effort to adjust the voltage by circuit design, the irregular stimulations on the TEG make it difficult to process only by the circuit. Here, we propose a simple approach to change the spike-like voltage to square-like profiles forming suitable voltage by connecting the TEG unit to an electrochemical ion-gel capacitor. The ion gel capacitor has a great advantage over the conventional capacitors because of easy control of capacitance by connecting multiple capacitors through printing them in a predesigned manner. The voltage profile of the TEG-ion gel system was modulated by contact frequency, contact area of the ion gel, type of ions, reduction/oxidation reaction, and connection type. We successfully demonstrated the light emission of printed electrochemiluminescence patterns. |
